Abstract:
To confirm the application safety of 17% Carbendazim?Thiram and 20% Thiram?Carbofuran suspensions on pepper,cultivation experiment in plastic house was conducted to study the effects of the two seed coating agents on pepper germination,growth,fruit qualities and the micro ecology in the rhizosphere soil.The results showed that Carbendazim?Thiram and Thiram?Carbofuran had no significant adverse effects on pepper germination and seedling growth,while compared with control,Carbendazim?Thiram decreased the height of pepper at squaring and flowering stage by 4.60% and 9.12% respectively;Thiram?Carbofuran reduced the content of chlorophyll at flowering stage,while Thiram?Carbofuran had no significant effect on the content of chlorophyll;both seed coating agents had significant effects on root activity of pepper,and compared to control,Thiram?Carbofuran decreased the root activity at seedling,squaring and flowering stage by 33.72%,78.05% and 55.88% respectively;compared to control,both Carbendazim?Thiram and Thiram?Carbofuran decreased the content of nitrate nitrogen in pepper fruit by 35.09% and 27.94% respectively;Carbendazim?Thiram and Thiram?Carbofuran influenced the micro ecology of pepper rhizosphere soil to different degrees,with significant effects on the activities of urease,phosphatase and catalase in the rhizosphere soil of pepper at seedling and squaring stage;Carbendazim?Thiram and Thiram?Carbofuran decreased the amount of bacteria in the rhizosphere soil of pepper to different degrees,while increased the amount of fungi;Carbendazim?Thiram decreased the content of available phosphorus in the rhizosphere soil of pepper,while Thiram?Carbofuran had no significant effect on available phosphorus.
